WHEEL,

Patented May. 24, 1910. 482,846.

To all :whom it may concern: .Be 1t known that I, JOHN L. JACKSON,

1 a citizen-of the United States, residing at.

"River Forest, in the county of Cook and --5 [State of Illinois, have invent-ed certain new }-and' useful Improvements in -Wheel's, of

" which the following is a specificatiom-ref erence being had to the accompanying drawin s."

i y invention relates to wheels adapted 1'0 be equipped with pneumatic tires, such as wheels for automobiles, etc. V Ithas .for its object to -provide anv improved wheel which will possess the} cominedadvanta es of the quick acting or quick detachable rim and those of what is knownas the demountable rim... 4 The advantages of a quick detachable tire haveflon'g been recognized-in the art, and ao sihce't l ieadvent of the demountable rim,

" its-advantages have also been well understood. Nevertheless, .so far as I am aware no one has heretofore provided a'satisfac tory construction in which 'the advantages :5 peculiar to the quick acting rim have been retained in a rim which was' also demountable .or capable of being removed'from the wheel with the tire. By my invention, how

ever, I provide a construction by which the 3orim'may be quickly demounted or removed with t-hetire in place, or'be equally quickly applied to the wheel, and also the tire may be'readily applied to or readily removed -.'from the rim which carries it. Thus all the advantages. of both styles of rim are secured.

' In the accompanying drawings,Figure 1 is aside view of an automobile wheel illustrating my-invention ;.Fig. 2 is a perspective view of a section'o'f a tire and a portion of the wheel illustrating .my improvements; Fig. 3 is an enlarged detail, being a horizontal section on l1ne-33 of Fig. 2; Fig. 4-. is an enlarged detail, being a sectional view on line 44 of Fig. 3 F1g. 5.is a pers ective view, showing another arrangement 'f r securing the parts of the rim together; Fig. 6 is; an enlarged partial cross-sectional view of the arrangement shown'in Fig. 5; so and Fig. 7 is a 'vlew showing the position and arrangement of the locking bolt by which the rim is. secured on the wheel.

Referring to the drawings, 7 indic zi tles 1e but is preferably the common. ti11 ipattern wooden wheel.

9 indicates a fixed rim in the form of an annular metal plate which is ermanently secured upon the felly 8. and pro ects slightly at eachside. thereof, as best shown in Fig. 2.- its inner margin the fixed rim 9 is provided with an upwardly-projecting flange "10, and at its outer margin is? provided with a downwardly-projecting flange 11. The

flange 11 is adapted to receive a bolt'12 for securlng a wedge platethereto', .as herein- Q after 1 described.

I 13' indicates a demou'ntable or-removable rim or tire supporting member, which carrles the usual pneumatic tlre composedof a casing 14 and an innertube 15. The the supportin member 13 is annular in form and fits of having internally-projectingflanges or suposely upon the permanent rim 9,

ports 1617 near its side "edges, as shown in Fig. 2. At its inner margin'the tire supporting member 13 is also provided with a epen ing flange 18, as shown in Figs. 2, 5 and 6-. By supporting .the demountable rim as described, aispace 19 is provided between the tire supporting member and the permanent rim, which receives the valve-stem 20 and'the nuts of. retaining clam s or lugs, if such are used. It will be un erstood that the tire supportingmember 13 is provided 'with a'suitable hole .for the passage of the valve-stem.

At its outer margin the tire supporting member 13 isvprovided with an upwardlyprojecting flange 21 of the pattern common. in clencher rims, being curved inward to engage the usual enlarged side edge 22 of the casing 14. The opposite side edge 22 is secured on the tire supporting member 13 by a detachable flange or ring 23 best shown in Figs. 2, 5 and 6. As therein shown the ring 23 fits upon the tire supporting memher 13 over the flange 18 and is provided with a groove in its lower outer edge forming a shoulder 24 which overlies the flange 10 when the ring is in operative position. The ring 23 is secured in place by means of an expansible J-shaped locking ring which engages the flange "18 and fits flush against the innei face of the tire supporting member and the lower portion of the ring 23,

its outer face being flush with the shoulder 24, as shown in Fig. 6.

In the construction shown in Figs. 2, 3

and 4. 25 indicates a locking ringthe ends of which are beveled, as shown at 2(3 in Fig. 3, so as to receivea wedge-plate 27 which is adapted to be secured to the tire supporting member 13 by a bolt 28, as best shown in Fig. 4. Obviously, by forcing the wedgeplate 27 laterally between the separated ends 26 of the ring 25, said ring is expanded and forced tightly into engagement with the flange l8 and the ring o r-flange 23. At this time the lower surface of the locking ring 25 is flush withthe lower surfaces of the flanges 16-17. It will be-understood, of course, that the locking ring 25 must be applied or removed when the tire supporting member 13 is demounted, but after the locking ring 25 has been secured in position the demountable rim may be readily applied to or removed from the wheel. When in position on the wheel the locking ring 25 and the wedge-plate 27 cannot become displaced as they are held ,in'position by the permanent rim 9 and the flange 10 thereof, which engages the locking ring 25 and limits the inward movement of the demountable rim. The locking ring 25 is provided with a notch 29 in its lower outer corner, as shown in Fig. 4;, to receive theflange 10. In Figs.

5 and 6 I have shown another, and my pre-- ferred, form of locking device for securingthe flange or ring 23 ,in position. In the latter construction I employ a locking ring 30 similar to the locking ring 25, except that the severed ends of the ring 30 are oppositely beveledin the form shown at 3132 in Fig. 5, thebeveled surfaces being inclined away from'each other downwardly instead .of away from each other outwardly as in the construction shown in Figs. 2, 3 and 4;. With the latter construction a wedge section or plate 33 is employed which is pressed upward between the separated ends of the locking ring 25, forcing them apart in the manner already described. The locking plate 33 is held in position by a bolt 34 which screws into the flange 18, as shown in Figs. 5 and 6. The head of the bolt 34 fits in a recess 37 in the under side of the wedge plate, as shown in Fig- 6, so that it' does not project below the lower surface thereof and therefore does not interfere with the applis cation of the demountable rim to the wheel.

The construction illustrated in Figs. 5 and 6 is preferable-because the bolt 34: cannot become accidentally detached, and, moreover, the wedge-plate 33 may be J-shaped the-same as the locking ring and thereby be better secured to the tire supporting member, whereasin the construction shown in Figs. 3 and 4 the lockingplate having the construction shown in Fig. 2 is'employe in order to permit of its removal by latesal movement.

It will be seen fromthe foregoing descripflion that the'removable rim is constructed supporting as. a Quick detachable rim and has all the advan age 'QITsuch a rim, and moreover, that when 1tls applied to the wheel it is impossible for the separable flange or ring thereof to get out of place.

The demountable -rimds, secured to the permanent rim by devices similar to those already described. That is to say, a J- shaped locking ring-38 is employed which hooks under the depending flange 11 of the permanent rimand engages the outer face of the demountable rim, lying under a shoulder 39 provided at that side of the demountable rim. The locking ring 38 is similar in construction and operation to the looking ring'30 and is secured in position by a wedge-plate 40 similar in all respects to the wedgeplate 33, except that the head 41 of the bolt 12 which holds it in place preferably extends below the lower surface of such wedge-plate.

In order to demount the rim it is necessary only to remove the nut 41 and wedgeplate 40, and detach the locking rin 38, when the entire rim with the tire heldiy it may be removed from the wheel. Another rim may then be applied, or if it be necessary to remove the tirefrom the demountable rim that can be'a ccomplished by remove ing the wedge-plate and locking ring 30, when the ring or flang and the tire drawn 0 ment.

That which I claim invention and I desire to secure by Letters atent, is,
